算法练习--判断连续相同字符串

查找相邻相同字符串

var found = false;function f(str){if(found){return;}var len = str.length;var a = str.substring(0,len/2);var b = str.substring(len/2,len);if(a == b && a!="" && a!=undefined){console.log("found: " + a+b);found = true;return;}for(var j = 1;j < len; j++){for(var i = j%2==0 ? j : j+1;i < len+2; i+=2){var c = str.substring(j,i);f(c);}}}f("abc9habcdefghjabcdefghj");if(!found){console.log("not found");}
